Your low ferritin level and those fancy terms like anisocytosis, hypochromic, and microcytosis are pointing towards possible iron deficiency. Target cells and thalassemia minor could also be in the mix here. Now, regarding your worry about cancer, especially breast cancer, it's important to know that these findings are more commonly related to issues like iron deficiency or thalassemia rather than cancer.

Keeping an eye on your menstrual cycle is good, and following up with the gynecologist can help clarify things further.
